A depth / rotational career by KV-H: a remarkably steady profile that scores 25 of 100, era-normalized against rush yds/g peers across 4 scored seasons, with a short career trimming the score.
Blend 26.4 × longevity 0.93 = KV-H 25· confidence 72%
Season-by-season quality (era-relative rush yds/g)
Reached 1% of the all-time Receiving Touchdowns leader — a rotational/depth all-time profile at the position.
A 0–100 scale where 100 = matched the all-time leaderat this position. Built only from visible encyclopedia data — career production vs. the all-time leader, plus efficiency (EPA) and comparable-player confidence — so it's a transparent context score, not a subjective rating. Tiers: Elite ≥ 85 · Strong ≥ 65 · Solid ≥ 45 · Depth < 45. Comparable-player confidence: 93%.
Production per snap — the box score normalized by opportunity. SIS is z-scored within running backs, shrinkage-regularized so small samples don't spike, over the NFL snap-count era (2012+).
Amber = this player (normalized to own peak). Indigo = average RBs aging curve. Group peak age: 21. Source: StatVault KV-H era (1999+).
